My invention relates to a device adaptable larger apertures B have their counterparts for giving multiple choice tests. One object in the apertures Ba of the member A", the is to provide a student self-grading device, smaller apertures B2 haveno such counteralthough I do not wish to be limited to this parts. It may be desirable, -tor economy in particular use of the device, since other apmanufacture, to punch the same apertures all 55 plications or uses thereof may be made and the wa throu h both sheets, but unless it is other objects will appear from time to time desire to mage the device reversible as to in the course of the speciication and claims. face, the apertures B2 are needed only on I illustrate my invention more or less diathe top sheet.

This sheet may be Referring to the drawings, A generally 1nmade to conform in shape to the members A 75 dicates a top face or side of an outer conand A2 and may beprovided at one end with tainer for the device. It may be folded over a cut away portion U, conforming to a similar or formed with flaps A1 which underlie the cut away portion Amin the members A and lower member A2 of the container. The flaps A2. Preferably it is so foi-nieder shaped as A1 may be formed with side portions or spacto be held against movement in relation to the 80 ing portions A3, whereby the members A and members A and A2 when it is inserted there- A2 are s aced apart a suitable distance to in. I may for example employ the seals permit tlie insertion therebetween of the A, which Kass about the edges of the memsheets later described. I do not wish to be bers A and 2 and hold the code sheet against limited to the employment of any particuescape or movement through the open end of 35 lar material, and I may employ, for examthe device. The sides A, onthe other three ple, sheet met-al, paper, liber, akelite and sides of the device, prevent any lateral movethe like.` ment of the code sheet. I illustrate this Referring to the top sheet A, as shown for method of holding the code sheet fixed as an example in Figure 1 I may provide it with example of a practical method, but do not 90 a plurality of aligned apertures. I illustrate wish to be limited specifically thereto except for example lines of apertures B arranged, so far as I limit myself precisely by the lan-- in the form of Figure 1, in vertical lines, each guage of my claims. The sheet C 1s formed such line bein given, if desired, some chars with a plurality of apertures Cg aligned with actcristic sym ol, as at B1. Interposed bethe apertures B and B3 of the members A and 95 tween each pair of lines of such apertures B is A2. If desired a mere perforation or weakanother line of apertures, preferably of like ening ofthe sheet may be employed to take the number, and herein shown of somewhat place of these a icrtures,butI prefer to aper- 2 smaller size, as at B. U n reference to ture the code s eets to permit the free pas- Figure 2 it will be seen t at whereas the sage therethrough of whatver punch may be 10 employed for marking the test or score sheet. Between the successive lines of apertures C2, and in line with the apertures B2 of the member A, the code sheet, when the score sheet is moved, is exposed to the apertures B2. In line with such apertures I may have indicating areas, such as the circles C, upon which the correct answer may be indlcated, as by coloring the correct area or by inserting any desiredniarking or symbol.

The score sheet D, as shown in Figure 7, may be. simply a blank sheet, or it may be p rovided with a plurality of weakened areas l, adapted to be aligned with the apertures B and B3 of the members A and A2, and of course with the apertures C2 of the code sheet. The score sheet D is so formed as to be permitted a range of movement Within the container formed by the members A and A2. Preferably this movement is so proportioned that when the score sheet is in initial position the weakened portions D1 are aligned with the apertures B, B" and C2. When the sheet is moved to its filial position, the weakened portions D1, or the apertures formed by punching them out, are aligned with the apertures B2 of the member A and the indicating areas of the code sheet.

In the operation of the device the score sheet is superposed upon the code sheet. It will be seen from Figure l that the apertures B are arranged in a plurality of groups or lines, in Figure 1 shown as twenty in number. The number of apertures in each group is constant, being for example shown in Figure l as six in each group. In the use of the device a test or set of questions may be propounded in multiple choice form, one question being provided for each group of apertures Ii, up to twenty, or for any smaller number, if desired. Each such question may be. answered by a plurality of alternatives, six or less. Assume for example, in testing color sensitivity, that the first question reads,

li'hat is the color of such and such an objecti (l) Red. (2) Black. (3) Brown. (4) Green. (5) Blue. (6) Yellow.

The individual taking the test inspects the object and decides that it is yellow and punches out the corresponding hole in the score sheet. If yellow is No. 6 in the list he punches out hole No. 6. He may then move the score sheet D to the right to the position in which it is shown in Figure 3. If he has punched out the correct weakened portion D1. it will overlie the marked area, on the code sheet. If the student has made a mistake. the punched out area will overlie a blank or unmarked area of the code sheet, and he can, if he wishes, return the score sheet for another test. Students may answer a whole group of such questions and then move the score sheet D to test position, or may make a check after eachanswer.

The seals A12 prevent any tampering with the device or any access on the part of the student to the code sheet. He may employ any desirable means, for instance the point of a pencil, for punching out the weakened areas D1. Once he has completed the test he can grade himself and mark his score, for example in the space B", or he can pass lthe device, still sealed, to the instructor, who can tell at a glance the correct score or mark.

The exposed portion of the sheet D is always exposed so that it may be grasped by the fingers of the operator.

It will be realized that whereas I have described and shown a practical and operative device, nevertheless many changes might be made in the size, shape, number and disposition of parts without departing from the spirit of my invention. I therefore. wish my description and drawings to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me to my specific showing.
